CORN-SHELLER.

Specification of Letters Patent No. 13,122, dated June 26, 1855.

To all whom it mag concern:

Be it known that we, ABRAM CLow and CHARLES N. GLOW, of Port Byron, inthe county of Cayuga and State of New York, have invented a new andImproved Corn- Sheller; and we do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe annexed drawings, making a part of this specification, in whichFigure 1, is a transverse vertical section of our improvement, the planeof sect-ion being through the center. Fig. 2, is a plan or top view ofditto, with one of the lids or covers thrown back. Fig. 3, is ahorizontal section of ditto, (00), (a2), Fig. 1, showing the plane ofsection.

Similar letters of reference indicate corresponding parts in the severalfigures.

The nature of our invention consists in the peculiar construction of theimplement as will be presently shown and described whereby the corn isshelled from the cobs, perfectly winnowed, or separated from chaff andother light impurities and discharged separately from the cobs. Themachine be ing also capable of adjustmentso as to accommodate ears ofcorn of diflerent dimensions.

To enable those skilled in the art to make and use our invention, wewill proceed to describe its construction and operation.

A, represents a rectangular box supported by a proper framing B. On theupper partof this box A, there is placed a transverse shaft O, whichruns in suitable bearings (a), (a). On the shaft 0, there is hung awheel D, which is cogged on its periphery and also cogged on its innerside. The side cogs gear into a pinion (b) on the upper end of avertical shaft E, and the other cogs gear into a pinion F, hung on ashaft G, which is placed transversely within the box A.

The upper end of the shaft E, has a series of teeth upon it as shown inFig. 1, and the lower end of the said shaft has a screw thread (cl) uponit. The shaft E, below the box A, is encompassed by a spiral conicaltube H, having an opening (6) at one side as shown in Figs. 1, and 3.The tube H, may be considered as a spiral or scroll, or a correct ideamay be conveyed by saying that the shaft E, is placed within it a littleout of center so that the space in dicated by the point (f) between theshaft and the inner side of the tube is rather wider than that at thepoint indicated by (9), see Fig. 3.

To the lower end of the tube H, there is attached a fan box I, having afan J, within it, said fan being attached or hung on an arm (h),connected to the shaft E, see Fig. 1. The upper part of the fan boxforms the bottom of the tube H, and is slightly in clined toward adischarge aperture The fan box I, is also provided with an aperture (j)directly underneath the aperture (i).

On the shaft G, there is hung a wheel K, which is permanently attachedto the shaft. The periphery of this wheel is slightly inclined orbeveled, see Figs. 1, and 3. To one side of this wheel there is attachedpins (75), (70), which fit in holes in the sides of a wheel L, placedloosely on the shaft G, so as to slide thereon. Around the shaft G,there is placed a spiral spring (Z) which keeps the wheel L, pressedagainst the wheel K, when said wheel L, is not acted upon by the ears ofcorn. The peripheries of both the wheels K, L, are provided with teethas shown in Fig. 2, and the periphery of the wheel L, is beveled, but ina reverse direction to the periphery of the wheel K. On one end of theshaft G, there is placed a fly wheel M, and on one end of the shaft (.3,there is a crank N.

The box A, is provided with lids or covers (m) one of which is providedwith a tube (n) which is directly over the space between the wheels K,L, and shaft E.

The operation will be readily seen. Power being applied to the crank N,the ears of corn represented in red are dropped, one at a time, down thetube The upper toothed portion of the shaft E, rotates the ears and thetoothed peripheries of the wheels K, K, shell the corn from the ears thewheel L, in consequence of the spring (Z) yielding or giving tocompensate for ears of varying thicknesses. The shelled corn falls tothe bottom of the tube H, and passes out of the aperture into a properreceptacle prepared to receive it, and a blast of air generated by thefan J, passes through the shelled corn as it passes into the receptacle.The cobs, also shown in red, fall, after having the corn shelled fromthem, to the bottom of the tube H, at the point f, and are carriedaround by the revolutions separately either of the parts hereindescribed for shelling the corn from the cobs,

for shelling wheels similarly constructed have been previously invented,but

l/Vhat We do claim as new and desire to secure by Letters Patent, is

WVe claim the tube H, in combination with the screw (cl) on the shaft E,arranged as herein shown for discharging the cobs separately from theshelled corn.
